What do French regulations say?
In France, extinguisher maintenance is governed by strict standards, such as NF S 61-919 and the decree of May 20, 1963. These texts specify that technical maintenance must be carried out by specialized, qualified personnel. This ensures that extinguishers comply with current standards and are ready for use when needed.
